On Saturday, 2021-04-17, Missouri DHSS announced that their de-duplication process removing antigen case counts for those who had an Antigen positive test and later had a positive PCR test was not working correctly. They removed approximately 11,500 cases, causing case counts to drop significantly. I’ve removed the 7-day average map below, and will replace it next Monday. 7-day average plots will show 0 new cases for most counties until then.

While the City of St. Louis, St. Louis County, and Kansas City provide day-by-day tracking of cumulative cases on their respective dashboards, the State of Missouri does not. The following tabs provide daily breakdowns of COVID data as well as additional statistics not included in the existing dashboards. Data are also provided for the wider St. Louis and Kansas City metro areas. Please note that the two average columns for reported cases and deaths are both seven-day rolling averages.
